Common Elephant Tusk

<em>Antalis entalis</em>, the common elephant tusk, is a marine mollusc in the class Scaphopoda, family Dentaliidae, classified as Least Concern by the IUCN Red List. The species is native to European waters and has been documented in Denmark, Norway, and Sweden, inhabiting subtidal and deep benthic zones of the northeastern Atlantic Ocean and North Sea. As a scaphopod, <em>Antalis entalis</em> is characterized by its distinctive curved, tusk-shaped shell that is open at both ends, allowing the animal to partially burrow vertically into sandy or muddy substrates with only the narrow posterior end projecting into the water column. The species feeds on foraminifera and other microscopic organisms in the sediment, capturing prey with specialized tentacle-like structures called captacula that extend through the broader anterior opening of the shell. Scaphopods have limited locomotion and typically remain partially buried throughout their lives. <em>Antalis entalis</em> plays a role in benthic communities as both a consumer of meiofauna and a prey item for predatory fish and invertebrates. Historically, elephant tusk shells of related species were used as currency and ornament by Indigenous peoples of the Pacific Northwest coast. Biological traits of this species remain poorly documented in the scientific literature.

common fleabane

<em>Pulicaria dysenterica</em> is a perennial herbaceous plant belonging to the family Asteraceae within the order Asterales. Commonly known as common fleabane or elecampane, this species typically colonizes damp, disturbed habitats including marshes, riverbanks, roadsides, and wet meadows. It is classified as Least Concern on the IUCN Red List, indicating stable and widespread populations. <em>Pulicaria dysenterica</em> is native to Europe and also occurs in the United States. The plant typically produces branching, woolly-stemmed growth reaching up to 60 centimeters in height, bearing yellow daisy-like flowerheads from mid to late summer that attract a range of pollinating insects. Its leaves are clasping and softly hairy, a characteristic that gives the plant a distinctly woolly appearance. Historically, the species was used in traditional medicine and as an insect repellent, with the common name reflecting both its reputed medicinal properties and the flea-deterring use of its dried foliage. Biological traits of this species remain poorly documented in the scientific literature.
